RAILWAY-RAIL STAY.

SPECIFICATION forming part of Letters Patent No. 782,568, dated February14, 1905;

Application fild November 28,1904. Serial No. 234,453. i

To all whmn itvnay concern:

Beit known, that L'EDWARD LAAS, of Otturnwa, in the county of VVap'ello,in the State .of Iowa, have invented new and useful Im- The object ofthis invention is to provide efiicient means for resisting thelongitudinal creepingof railway-rails and which shall be adapted to beapplied to rails of different sizes; and to'thatend the inventionconsists in the improved construction of the rail-stay hereinafterdescribed, andas illustrated in the accompanying drawings, of whichFigure 1 is a transverse section of a railwayrail equipped with myimproved rail-stay. Fig. 2 is a sideview of the same. Fig. 3 is adetached plan view of the supporting-bar of the rail-stay. Fig. Lis atransverse section on the lineX X-in Fig. 1. Fig. 5 is a transversesection on the line y y in Fig. 3. Fig. 6 is an isometric view of one ofthe rail-gripping jaws, and Fig. 7 illustrates a modified form of myimproved rail-stay.

' In the said drawings, A represents one of the cross-ties which supportthe track-rails, (represented at R.)

The essential features of my invention consist of the bar a, whichextends across the under side of the rail R and is formed with I theseat I) for said rail and with extensions 0 c at opposite sides of saidrail-seat, the railgripping jaws J J, mounted on the extensions 0 0,movable toward and from the rail-seat Z),

and suitable means for forcing the said jaws toward the rail-seat so asto securely grip the flanges (Z (Z of the rail R. The object of thisconstruction and combination of elements is primarily to adjustablysupport both railgripping jaws on a rigid and inflexible bar providedwith a continuous bearing across the under side of the rail, and thusaffording to the rail-gripping-jaws perfectly secure supports which arepermanently joined to each other and maintained in their respectiveplanes. I connect the jaws J J to the extensions 0 0 by means ofsuitable interlocking longitudinal and formed with longitudinalshoulders ff on the inner sides of the said slots, as shown in Figs. 2and I of the drawings.

Each of the jaws J, I form with a depending tongue g, which extends intothe slot 8 and is provided with longitudinal grooves 7t, 5 which engagethe shoulders ff, so as to retain the jaw seated on the exte'nsion o ofthe bar a. The tongues g g are provided with perforations t", which arein a line parallel with the groove 6 and receive through them 7 theadjustable coupling-bolt t', which is pro vided on its opposite endswith a head and a nut j, said bolt tyingthe tongues g g to each other,and by tightening the nut j the jaws J J are forced toward the rail-seatZ) to firmly grip the flanges (Z d of the rail R.

'I provide the bar a with deep and substantial side bearings Z Z forabutting against the side of the cross-tie in opposition to thelongitudinal stress of the rail. Said side bearings consistof verticalwalls, which extend, preferably, the entire length of the bar a and itsextensions 0 c and are disposed with the aforesaid slots 6 0 betweenthem.

.To render the rail-stay adjustable to'differ- 5 cut sizes of rails, Iform the tops of the extensions 0 0 inclined toward the rail-seat Z) andform the bottoms of the jaws J J correspondingly inclined, asillustrated in Fig. 1 of the drawings, in which the dotted lines showthe 9 jaws adjusted to grip a rail larger than the rail R represented infull lines. 'It will be observed that this is effected by setting thejaws J J farther from the rail-seat, in which adjustment the jaws becomeseated on higher portions of the tops of the extensions 0 c, and thusfitted to theincreased thickness of the base of the rail. To permit saidadjustment of the jaws J J without causing the bolt '5 to be lifted, andthus obviate the necessity of weakening the bar a by forming it with agroove to accommodate the bolt, 1 elongate vertically the perforationsin the tongues g of the jaws, as

shown in Figs. L and 6 of the drawings.

What I claim as my invention is 1. The improved rail-stay consisting ofa bar abutting against the side of the cross-tie and formed with arail-seat and with extensions at opposite sides of said seat, andrail-gripping jaws mounted on said extensions movable toward and fromthe rail-seat, and means for forcing said jaws toward the said seat.

2. A rail stay consisting of a bar abutting against the side of thecross-tie and formed with a rail-seat and extensions at opposite sidesof said seat, rail-gripping jaws mounted on said extensions movabletoward and from the railseat and connected to said extensions byinterlocking longitudinal joints,and means for forcing the jaws towardthe rail-seat.

3. A rail -stay consisting of a bar abutting against the side of thecross-tie and formed with a rail-seat, extensions at opposite sides ofsaid seat and slots extending lengthwise of said extensions,rail-gripping jaws seated movably on the extensions and formed withdepending tongues extending into the aforesaid slots, and an adjustablecoupling tying the tongues to each other.

4. A rail-stay consisting of abar abutting against the side of thecross-tie and formed with a rail-seat, extensions at opposite sides ofsaid seat, slots extending lengthwise of said extensions andlongitudinal shoulders in the sides of the slots,- rail-gripping jawsmounted movably on the extensions and provided with tongues extendinginto the aforesaid slots and formed with longitudinal grooves engagingthe aforesaid shoulders, and an adjustable coupling tying the tongues toeach other and forcing the jaws toward the rail-seat.

5. A rail-stay consisting of a bar formed with a rail-seat, verticalwalls extending from opposite sides of the rail-seat and disposed toabut against the side of the cross-tie and formed with shoulders ontheir inner sides, railgripping jaws mounted movably on the aforesaidwalls and formed with depending tongues disposed between the walls andformed with grooves engaging the shoulders of the walls and providedwith perforations in a line parallel with the said walls, and a boltpassing through the perforations and provided with a head and a nut onits ends, as set forth.

6. A rail -stay consisting of a bar formed with a rail-seat, extensionsat opposite sides of said rail-seat and with hearings on said extensionsinclined toward the rail-seat, rail-gripping jaws mounted movably onsaid bearings, and means for forcing thesaid jaws toward the rail-seat.

7. A rail stay consisting of a bar formed with a rail-seat, extensionsat opposite sides of the rail-seat, hearings on said extensions inclinedtoward the rail-seat and vertical slots extending lengthwise of theextensions and formed with longitudinal shoulders in the sides of theslots, rail-gripping jaws mounted movably on the inclined bearings andprovided with tongues extending into the slots and provided with groovesengaging the aforesaid shoulders, and means applied to said tongues forforcing the jaws toward the rail-seat.
